Hi Anna,
Your message is not clear:
1) do you mean you are adding more data POINTS or data SERIES
how many data point & data series do you already have (approximately)
2) how are you adding? the reference to the OK button is unclear
best wishes

Hi, I'm trying to add more variables to be showing on the chart, but after
I've added some, I cannot add any more! I select them, but cannot
confirm,
the OK button is dull. Any help is appreciated
